Resolution No.2 (1973): Frequency range of artificial electromagnetic emissions

IAGA, recognising the importance of the continued study of natural electromagnetic phenomena and the fact that man-made sources of electromagnetic energy continue to increase in a way that tends to obscure these natural phenomena, recommends that adhering countries make an effort to set aside reservations in which man-made sources of electromagnetic energy in the frequency range of interest to IAGA are excluded so as to preserve such areas in which natural electromagnetic phenomena can be studied in years to come.
